Also known as Byrd Creek Bridge, this concrete stone arch bridge is the centerpiece of the Cumberland Mountain State Park near Crossville, TN. Here, a dam was built on Byrd Creek forming a lake on the southeast side. Highway TN419 carries the seven span bridge which is listed on the National Register of Historic Places as part of the Cumberland Homesteads Historic District. Byrd Creek Dam is the largest masonry structure ever built by the Civilian Conservation Corps. Here is the text of the nearby historic marker:

Men of the Civilian Conservation Corps' Company 3464 built this unsuspended bridge between 1935 and 1940, for a 30-acre impoundment of Byrd's Creek. Three thousand five hundred and fifty cubic yards of dirt and rock were excavated and the core, containing 8,000 tons of concrete, is faced with Crab Orchard stone for the 319-foot span. Seven spillways, rising 28 feet above the stream bed, carry the 18-foot roadway approximately 16 feet above water level.
